Parasitic myelopathy caused by Gurltia paralysans in domestic cats is a disease commonly reported in several South American countries. The adult parasite is lodged in the meningeal veins and spinal cord, often causing clinical manifestations of vascular proliferation, thrombophlebitis, and medullary compression. Wild felines are believed to be the definitive hosts of this parasite. The infection occurs through the ingestion of paratenic hosts, but the life cycle of G. paralysans is not yet clearly understood. In this paper, we discuss a case of parasitic myelopathy in a margay (Leopardus wiedii) that died during post-surgical care. Necropsy revealed focal hemorrhages in the thoracolumbar spinal cord. A microscopic examination revealed adult nematodes and eggs inside the veins of subarachnoid space in spinal cord, suggesting G. paralysans infection. This is first description of parasitic myelopathy in a margay in Brazil.
家猫体内由麻痹古氏线虫（Gurltia paralysans）引起的寄生性脊髓病是南美几个国家常见报道的一种疾病。成年寄生虫寄生于脑膜静脉和脊髓，常引发血管增生、血栓性静脉炎和髓质压迫的临床表现。野生猫科动物被认为是这种寄生虫的终末宿主。感染通过摄食转续宿主发生，但麻痹古氏线虫的生命周期尚未完全清楚。在本文中，我们讨论了一例在术后护理期间死亡的虎猫（Leopardus wiedii）寄生性脊髓病病例。尸检显示胸腰段脊髓有局灶性出血。显微镜检查发现脊髓蛛网膜下腔静脉内有成虫和虫卵，提示为麻痹古氏线虫感染。这是巴西首次关于虎猫寄生性脊髓病的描述。
